Only the Bluetooth restricts the choice. But I want to hear without ever being tied to a cable on my Tablet Internet Radio.
After I've been listening to a lot of Active I realized that the boxes either had a good sound to akzetapelen then but too expensive, ugly black boxes, or were without Bluetooth.
So it remained only Z600. They are supplied with a Bluetooth dongle, no real bonus. Sorry, this just sounded at the low bit boring, especially in contrast to BOSE speakers, the bass there were too dominant to me. The boxes have been recognized by my Samsung tablet immediately. Only my laptop been 5 years old ACER can not do anything with the dongle.
Conclusion:
Super unique design, Bluetooth music enjoyment without cable, good workmanship is high quality, good accessory with jack cable and a reasonable price. Unfortunately, in the bass a little limp.
